COIN-COLLECTOR FOR TELEPHONE SYSTEMS.

Specification of Letters Patent.

Patented June 13, 1911.

Application filed June 4, 1910. Serial No. 564,922.

- an outlying station, so that the central operator may easily and accurately ascertain such denomination.

An important object of this invention 1s to provide a coin collector which is simple in construction, positive in its operation and cheap to manufacture.

A further object of this invention is to provide a device of the above character, so

constructed that a selected number of dis tinct and separate sounds will be given, when a proper coin is deposited within the same.

A further object of this invention is to provide a coin collector, which will enable the operator at the central station to readily ascertain the denomination of the coin deposited within the coin collector.

Further objects and advantages of this invention will be apparent hereinafter.

In the accompanying drawings, forming a part of this specification, and in which like numerals are employed to designate like parts throughout the same, Figure 1 is a central vertical section through the device, parts thereof being shown in side elevation. Fig. 2 is an end view of the drum or cylinder shown in Fig. 1, and showing diagram- Fig. 3 is a diagrammatic view of the stationary contacts, showing the same arranged in different vertical planes.

In the drawings, wherein is illustrated a numeral 1 designates a casing which is preferably rectangular and formed of sheet metal or other suitable material. The rear wall of the casing 1 is provided near its mally closed by means of a door 2. The forward wall of the casing 1 is provided near its upper end, as shown at 3, with a suitable opening to rotatably hold a transverse horizontally disposed shaft 4:, the inner end of which is rotatably mounted within a bracket 5 fixedly secured to the rear wall of the casing 1 as shown at 6. The rear end of the shaft 4 extends beyond the bracket 5 and is provided with a crank 7, to which is pivotally connected one end of a retractile coil spring 8. The upper end of this spring is connected to an eye bolt 9, which is rigidly secured to the rear wall of the casing 1. The forward end of the shaft 4: is provided with a crank 10, upon the free end of which is arranged a knob 11. The knob 11 and crank 10 serving as means whereby the shaft A may be manually rotated. The shaft 4 is provided inwardly of the casing 1 and adjacent the crank 10 with av ratchet wheel 12, which is rigidly secured to the same. A pawl 13 is pivotally mounted upon the forward wall of the casing 1, as shown at 14, to engage the ratchet wheel 12, as clearly shown in Fig. 2. By this construction it is obvious that the shaft 4 may be rotated clock-wise, but that the same cannot be rotated in the opposite direction, on account of the pawl 13 and ratchet wheel 12.

Rigidly mounted upon the shaft 4" is a rotatable member or drum 15, which is provided with a radially disposed slot 16 extending through the ends 17 of the same. Within the slot 16 and adjacent its forward end is disposed a pocket 18, having spaced side walls 19 which are secured to the side walls of the slot 16 by means of screws or the like, as shown at 20. A pin 21 is arranged adjacent the rear end of the drum 15, within the slot- 16 .and near the inner end of the same, as clearly shown in Fig. 1. Upon this pin is pivotally mounted a contact arm 22, provided near the pin 21 with an apertured ear 23, to which is connected one end of the retractile coil spring 24, the opposite end of which is connected to a bracket 25, which in turn is rigidly connected to the pocket 18, as shown at 26. The contact arm 22 is disposed within the slot 16 and is capable of oscillating within the same. The contact arm 22 is normally held in its lowermost position by the spring 24:, and the same is moved from such position by the insertion of a coin within the pocket 18. The casing 1 is provided at its upper end and adjacent its forward side with a chute 27, within which a coin is inserted when being directed into the pocket 18. A track 28 is provided at its upper end with an arm 29 which in turn is provided with a base 30 to be rigidly connected to the top wall of the casing 1, as shown at 31. The track 28 is substantially semi-circular and has the same curvature as the periphery of the drum 15. This track is disposed adjacent the rear end of the drum 15.- As clearly shown in Fig. 2, the lower end of the track 28 is curved or bent forwardly, as shown at 32.

At the right of the drum 15 are disposed contacts 33, 34 and 35, which are supported by and insulated from the rear wall of the casing 1. The contacts 33 are two in number and are disposed in the same vertical plane. There is only one contact 34 which is disposed in a vertical plane rearwardly of the first named vertical plane and there are three of the contacts which are disposed in the same vertical plane, and which, in turn, is rearwardly of the second named vertical plane. The contacts 33 are disposed nearest the periphery of'the drum 15, the contact 34 a little farther removed and the contacts 35 at a distance outwardly of the contact 34. The contacts 33 and 35 have their ends terminating in arcs which are concentric to 'each other and to the drum 15. The contacts 33 are connected in series with a wire 36, the contact 34 is connected to a wire 37 and the contacts 35 are connected in series by a wire 38. These wires are connected to a common wire 39 as shown at 40. The wire 39 is connected to a contact 41, which forms a portion of an induction coil, comprising primary and secondary windings .42 and 43. The primary winding 42 has one end thereof connected to a post 43, which has electrical connect-ion with a vibrator 44 adapted to engage the contact 41.

' the secondary winding 43, as above stated,

and this winding is connected to wires 51 and 52 which lead to the central station. The wire 52 is provided with a condenser 53, which is generally provided in a talking circuit. I

In the operation of the device, if the call which is desired to be made costs ten cents, the subscriber deposits a dime, designated 7 in Fig. 1 by the numeral 54, within the chute 27 and the same travels downwardly and is deposited within the pocket 18, whereby the contact arm 22 is raised from its lowermost position. The subscriber then turns the drum clockwise to bring the contact arm 22 into successive engagement with each of the contacts 33. When the contact arm 22 engages each of the contacts 33 a circuit is completed through the wire 36, through contacts 41 and 43 and the vibrator 44 into the primary winding 42 to one terminal of the source of current. The current flows from the positive terminal of the source of current through the wire 46, through bracket 5, ring 48 and the wire 49 to the contactarm 22. The current then flows through the contact arm to the contact 33 and again to the wire 36 as above described. As long as the arm 22 is in engagement with each of the contacts, the vibrator 44 is set in motion which produces a buzzing sound. Analternating current is induced in the secondary winding 43 and flows through the wires 51 and 52 which constitute the talking circuit between the subscriber and the operator at the central oflice. The operator is thus able to hear the buzz ofthe vibrator. Since there are two of the contacts 33, the operator at the central station will hear two separate and distinct buzzes of the vibrator, whereby it will be known that the subscriber has deposited a ten cent piece. If

contact arm 22 will be oscillated to engage the single contact 34, and the operator at the central station will only hear a single buzz. Similarly if a quarter has been deposited, the contact arm 22 will engage successively the three contacts 35, to cause three separate buzzes of the vibrator. After a coin has been deposited within the pocket the subscriber-deposits a five cent piece, the

18, the same is held by the arm 22 until the track 28 until said arm has completed its engagement with the stationary contacts. After the drum 15 has been rotated clockwise for a little more than a half of a revolution, the spring 8 will return the same to its normal position, whereby the contact 7 arm 12 will slip ofi of the upper end of'the track 28 and be oscillated forwardly by a spring 24, to assume its lowermost position. The drum 15 is capable of being rotated in one direction only, on account of the pawl 13 and the ratchet wheel 12, as above described.

We wish it understood that the form of our invention herewith shown and described is to be taken as a preferred embodiment of the same, and that certain changes may be made in the form, size and arrangement of parts without departing from the spirit of our invention, as set forth in the annexed claims. a
